Sorption Studies of Uranium and Thorium on Mesoporous MCM-41: Effect of Synthesis Conditions

In this study, mesoporous MCM-41 have been prepared in various conditions with cetyltrimethylammonium bromide (C16) and dodecyltrimethylammonium chloride (C12) as template and characterized by powder X-ray diffraction, N2 adsorption-desorption measurements. Sorption behavior of uranium and thorium on these adsorbents have been compared and discussed. The results show Kd value of uranium on the synthesized mesoporous MCM-41 by C12 has been enhanced and the synthesized adsorbents by hydrothermal method have more sorption affinity for thorium than the synthesized adsorbents by non-thermal method.
